If the design calculations fully consider the impact of all constraints, support may also be considered tangential arrangement. In this way the structural support, under the temperature and contraction, bearing displacement tends to polar coordinate direction. Tangential way activities will be bound (bound activity), bearing chant tangentially oriented and able to withstand the horizontal forces, the sum of these binding, depending on the size and structure of the stiffness curve radius. The binding may be quite large, and the other must force (braking force, wind and inertial forces) is superimposed by a vector. In short steel ball bearings, usually due to the sliding part of the activities and the rotating part of the bearing are separated, while bearing in displacement, but also can be applied to each rotation, as long as the bearing design takes full account of the displacement of the binding of the branch the role of the beam seat, the two seat arrangement system are available. Piers is a relatively newly plate pier, bridge set up a central fixed bearing, fixed bearing support on the remaining side pier, located one-way bearing activities tangentially, on the other side set up multi-directional sliding bearings, abutments in fixed bearing side, set up a one-way activity laminated rubber bearing tangentially, on the other side to set up multi-laminated rubber bearing activities. Piers is a relatively newly pier plate, set a fixed central bridge abutment, piers and abutments remaining in the fixed bearing side, set up a one-way direction tangential bearing activities, and the rest are located more to the active support. For full-bridge laminated rubber bearings are used, the polar direction layout: pier plate is relatively rigid pier, bridge set a fixed laminated rubber bearings, located more to the activity on the other side laminated rubber bearings, bridge Taiwan-way activities are set up along the polar direction of laminated rubber bearings. Deck hinge narrow curved continuous girder bridge (eg ramp bridge) can also be arranged on the middle pier located monopile, try to set the double seat at the end of the beam to the Union, in order to withstand the torque WJGZ, the bearing beams curve lateral deviation to the curve, torque adjustable beam cross section. Seismic steel ball bearing type using casting under vulcanization conditions at room temperature from up to 6 ~ 10Mpa, high strength of this silicone rubber; good aging resistance, particularly excellent resistance to ozone aging properties; oil, excellent wear resistance steel ball seismic grid bearing manufacturers offer, commonly used in the jack ring; reasonable price; by trial spherical grid damping steel bearing, polyurethane rubber used to increase the tensile strength of filling up 12.75Mpa, elongation at break of up to 380% since the vulcanized rubber hardness Shaw 89 degrees. Filled polyurethane rubber can increase seismic steel ball bearing structure is consistent with the rubber bearing basin, but its basin ring height should be based on the need to increase the amount on the line heightening, while reserve pressure injection of liquid steel at the pelvic floor polyurethane rubber channels, For times increase, we need to set aside more than one hole. Filled adjustable shock urethane rubber ball bearing steel structure design should take full account of the following construction details: bearing rubber sheet steel pots and quality control of the pelvic wall tolerances should be tight, should ensure that the filling liquid polyurethane rubber bearing, the seal reliable, ensuring no leakage of rubber; bearing basin ring stress checking calculation should take into account the additional stress after pressure reduction caused by thickening of the rubber sheet; channel set on seismic steel ball bearing filling liquid rubber floor, should be easy with the external piping connection, in order to increase the construction site operations; seismic grid of steel ball bearings, steel ball bearings, steel ball bearings Guangrun cards provided by Hengshui Rubber Co.
